"oh no, how could I possibly calculate the time elapsed?". You could but...don't do that... calculate the force, and multiply it by the distance.

Sr. Janice will have done a total of 91,764 joules of work. To get this, we first convert 130kg in newtons to get 1274.50 newtons. Since work is calculated by multiplying force by distance, we multiply 1274.50 by 72 to get 91,764 joules.
